Help/Support Parse JSON in Objective-C?

[niro 1.2k 9 9.1.0]

Hello, as some of you may know I am trying to turn my IG exploits into a reality, but I am having trouble with parsing/returning JSON from a URL response. Here is an example

 

 

lets say I submit this to a server

firstname=first&lastname=last&age=99

and the response from the server is this

{  
   "person":{  
      "firstname":"first",
      "lastname":"last",
      "info":{  
         "age":"99"
      }
   }
}

how would I retrieve this information (certain elements)

 

lets say I JUST want the persons age so the return string should be just "99"

or how do I JUST return the lastname or JUST the firstname, another thing how would I pass the returned element into the next POST request without the user having to type it again?

 

if anyone can find an example that would be fantastic

 

Thank You!
